One of my buy box requirements is the house needs to cashflow at least $500 per month or I am not buying it. 

Down Payment + Closing Costs = Cash to Close.For your purchase contract, I'd have suggested an escalation clause requiring proof of next best offer upon acceptance.

Lots of people who have trailers don't own the property they are on and sell them.As for the owner of the land expecting tenants to do repairs-there shouldn't be many repairs required to the land, just the trailer that is on it (which your grandmother owns and should be responsible for maintaining). 

No personal income or tax returns are required.

@Crystal Wilson Do some states require you need a agent?

One of my wholesale lenders used to be willing to finance these, I can't remember the CLTV requirement of the top.

Below is the link of the property:https://www.loopnet.com/Listing/927-Dixon-St-Tiptonville-TN/...No idea why it would be listed in the title unless the owners took some kind of government incentive that requires them to only lease to section 8 tenants.

Most lenders won't require an application fee and should be able to clearly lay out their financing costs, cash to close, and projected profitability for you.I hope this helps.

FHA loans require living in the home as your primary residence for 1 year after purchase.

All buyers and sellers of rental real estate should require Tenant Estoppel Letters in their contracts.
